AMIS-710216: 200dpi Two Level Digital Output Module
Data Sheet
The AMIS-710216 module consists of 11 sensors that are cascaded to provide 704 photo-detectors with their associated multiplex
switches, and a digital shift register that controls its sequential readout. Mounted in the module is one-to-one graded-indexed micro lens
array that focuses the scanned documents to image onto its sensing plane. A buffer amplifier amplifies the video pixels from the image
sensors and passes them to analog digitizing circuit, where the video pixels are converted to digital signal and passed to output of the
module. See Figure 1, the block diagram of the AMIS-710216 module.
Illumination is accomplished by means of an integrated LED light source. All components are housed in a small plastic housing with a
cover glass which acts as the focal point for the object being scanned and protects the imaging array, the micro lens assembly and the
LED light source from dust. The pictorial of AMIS-710216 cross section is shown in Figure 2.

I/O to the module is an 8-pin flex cable connector (see I/O Connector, under Specifications) located on one end of the module. The
connector is on the top of the module with the glass window facing down and it is located on the opposite side of the module. See the
Mechanical Housing under Mechanical Structure.
